SPRING-TIRE FOR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented Mar. 2d, 1914.

Application filed October 18, 1912. Serial No. 726,434.

To all whom. it may concern Be it known that I, JOHN W. citizen of the United States,

ewburgh, county of Orange, and State of New York, have invented certaintnew and useful Improvements in Spring-Tires Vehicle-Wheels, of which the following is a specification.

This invention relates to spring tires for vehicle wheels.

My object is to provide an improved spring the of the type employing coiled springs interposed between the wheel rim or felly proper and the floated tire rim movable inrelation thereto, and to this end it provides, first, an improved arrangement of the springs whereby, in addition to affording a spring support for the Wheel, the impact of the wheel with any object is cushioned,

direction in which it is moving, and a certain adaptability to yield sldewise, as when turning a curve, is permitted; second, the invention provides a LEONARD, a residing .at

novel telescopic guides interposed between the wheel rim and the tire and tire rim are prevented from having undue lateral wheel is turning a curve.

The invention is set forth fully hereinafter and the improved and novel features thereof are recited in the appended claim.

Inthe accompanying drawings: Figure 1 is a longitudinal section through a portion of a spring tire made according to the present invention; and Fig. 2, an enlarged cross section on line 2-2, Fig. 1.

The wheel 1 is provided with a preferably metallic tireor rim 2.

At 3 is shown a tire rim which carries a suitable tire 4, preferably of rubber and preferably. provided with embedded, circumferential, reinforcing wires 5. Circular or leather or other suitable fabric 8 is clamped between the wheel felly 1 and the rim or tire 2, the end parts thereof being secured between the clamp plates 6 and the rim 3. This fabric casing 8 extends entirely houses the springs and other parts interposed between the wheel 8 1s adapted and the rim 3 and, being flexible, the casing as the rim 3 and tire 4 move inwardly or outwardly in relation to the wheel.

Secured to the rim 3 by any suitable means, such as rivets 9, are a plurality cups 10 arranged at intervals around the wh Secured by any suitable fastening, such as screws 11, to the tire 2 and arranged opposite the cups 10, are the abutlocks or castings 12 Which are pro vided with cups 13 at their ends and with an" intermediate cup 14. Seated in the cups l0 and 14s are springs 15, there being provided a number of these springs at intervals around the wheel.

Suitably secured to the rim 3, as by screws 16,

abutment blocks 12 and which have cups 18 at their end parts disposed opposite the cups 13 and central cups 19. prings 20 have their ends received in the cups 13' and 18.

centrally of th plungers 21 and cylinders 22. Preferably, rubber or elastic cushions 26 are located in the cylinders 22. The springs 15 heel, H to their inclined position, adapted to cushion the shock or impact on the tire when an obstacle is encountered, whether the wheel be going forward or backward. The plungers 21 and cylinders 22 constitute guiding means to resist too great lateral inclination or displacement of the tire 4 in relation to the wheel, but at the same time the fact that the springs 15 and 20 are free, permits considerable relative lateral displacement so that a suitable cushioning action is had as the wheel turns a curve. The cups anchor the springs and prevent them from becoming displaced. The arrangement ofsprings combination with the wheel proper and abutment blocks shown in Fig. 1 is continued in the order disclosed in Fig. 1 comheel.

pletely around the w Having thus described my invention;

I claim as new and desire to secure by ters Patent, is

Ina spring tire for vehicle wheels, the

and a tire movable in relation thereto, of abutment blocks carried by the wheel and the tire and arranged in alternation, said abuts ment blocks being provided with inclined cups at their end parts and a cup at their What Letcenter part, inclined coil springs whose ends are seatednn and retained by the cups at the JOHN W. LEONARD. Witnesses:
